Eksperimentell: Heart Rate Variability Biofeedback (HRV-B)
The HRV-B intervention will consist of five weeks of daily HRV-B practice, based on previous empirical studies that used 5 weeks (Tatschl et al, 2020) with 6 weekly lab visits or checkins.
Participants will practice for 10 minutes in the morning and evening for a total of 20 minutes per day, using a wearable device and mobile app.

Aktiv komparator: Music Listening
The control group will undergo a 5 week active control intervention consisting of daily music listening and 6 weekly check ins.
Control participants will listen to music through an app for 10 minutes in the morning and 10 minutes in the evening, for a total of 20 minutes daily, using a mobile app.
They will be instructed to avoid doing other tasks when listening to the music to ensure consistency between individuals.

State Paranoia
Tidsramme: 5 weeks, 6 data points

|
Psychotic Symptoms
Tidsramme: 5 weeks, 2 data points
|
The Chinese version of the Positive and Negative Symptom Scale (PANSS) evaluation will be conducted by a trained assessor during intake and at the final visit to rate the severity of the patient's psychotic symptoms.
Minimum score: 30 (minimal psychotic symptoms) maximum score: 210 (severe psychotic symptoms).

Heart Rate Variability (HRV)
Tidsramme: 5 weeks, 70 data points
|
RR Intervals (time between heart beats) are automatically stored in the Elite HRV app after every training session.
Additionally, SDNN and RMSSD as measured in the EliteHRV app will be extracted from each training session during the weekly checkins.

Ideas of Reference
Tidsramme: 5 weeks, 2 data points.
|
The Chinese version of the Ideas of Reference Interview Scale (IRIS) will be administered to participants by a trained assessor on the initial and final lab visits.
Minimum score: 0 (no ideas of reference), maximum score 15 (endorsement of all 15 themes).
